But you'd think for a major port they'd have other types of backups not ship supported but based on maintaining the safety of the port. Like if a major ship goes dead and starts free floating in the port, isn't there safety protocols or systems in place to deal with that? Tug boats, anchoring, emergency power, support ships or something .... even if it cost millions, it's better than spending millions in recovering from a destroyed bridge and lives lost.
Ships accidentally running into bridges is a fairly common event. Most of the newer bridges have a diamond of protective rubber barriers surrounding the supports. And all ports will typically have tug boats to guide them past a certain point.
However, those are typically kept in or near the actual port, and probably take a while to get anywhere far from shore. This is probably at some level a fault of the ship and their crew. It could be a failure to keep their equipment in working order, but the majority of near port collisions are due to ships not following or knowing the ports guidelines on speed or navigation.
I find it a bit odd that they would blame it on losing power, but they still managed to hit it head on with enough speed to knock it over.
You do understand ships will keep moving after the engine quits, right?
Right.... But they aren't operating in vacuum. Ships that large take a while to get any speed and lose it relatively quickly, they are moving a lot of water.
Ive since looked at the video, and it does clear things up a bit. Looks like they lost power and slowed, but when they regained power the engines were still engaged, causing them to pick up speed again.
Afterwards the power cut once again as they neared the bridge. When they came back on they threw the engines into reverse, which is what caused the bow to drift starboard
You’re very wrong here. These ships don’t lose speed quickly. They can take MILES to stop. Some of the heaviest vehicles on earth with the most momentum and they are designed for effective displacement.

At full speed.... There is a huge difference between 5 and 24 knots.
A ship is supposed to be able to brake within 15 times their full length at full speed.
My original concern was with the fact that they hit the bridge head on without power. Meaning they were already close to the bridge when they lost power and presumably steering towards the pile when they lost power.
I could see them losing power and drifting into the support, but couldn't really make sense of the head on collision. If they had been close enough to ram with just momentum, one would presume steering before they lost power would have already been be oriented.
Like I said, watching the video cleared things up, the operator threw it in full reverse, which forced the bow starboard.
As an emergency system, you could fire drones at the ship that embed or magnetically attach themselves near the water line, to change the flow direction.
Obviously this requires a simulation that you trust to pick a better path and not make things work.
It would be like when you’re in a canoe and need to make an emergency turn and you just jam your paddle over the side and crank on it like a pry bar.
There’s got to be some way of quickly deploying a new fin to a moving ship to change its heading.
